Width = w=?
Length = l=(3w+8)cm
Perimeter = p = 128cm
Perimeter of a Rectangle = length + length + width + width
Perimeter of a Rectangle =2 length +2 width
P = 2l +2 w
128=2(3w+8)+2w
128=6w+16+2w
128-16=8w
112=8w
112/8=8w/8
14=w
w=14
Width = w= 14cm
Length = l=(3w+8)=3(14)+8 = 42+8 = 50cm

Answer:
6.2* 10 ^-24
Step-by-step explanation:
(2.0 ⋅ 10−4) ⋅ (3.1 ⋅ 10−20)
Multiply the numbers
2.0 * 3.1 =6.2
Add the exponents
10 ^-4 * 10 ^-20 = 10 ^( -4+-20) = 10 ^ -24
Put back together
6.2* 10 ^-24
The number is in scientific notation since there is one nonzero digit in front of the decimalv
